Exhaust pipe device capable of purifying gas

Abstract

The invention relates to an exhaust pipe device capable of purifying gas. The exhaust pipe device comprises a main exhaust pipe, an auxiliary exhaust pipe, an electromagnetic valve and a silencer, wherein the auxiliary exhaust pipe is arranged at the upper end of the middle part of the main exhaust pipe, and is inversely U-shaped; two pipe orifices at the lower part of the auxiliary exhaust pipe are connected with the main exhaust pipe; the electromagnetic valve is arranged at the middle part of the main exhaust pipe and is located between the two pipe orifices at the lower part of the auxiliary exhaust pipe; the electromagnetic valve controls the middle part of the main exhaust pipe to be opened and closed; the silencer is connected to one end of the main exhaust pipe; a gauze screen is arranged at a joint of the silencer and the main exhaust pipe; and a smoke filter is further arranged on the main exhaust pipe and is used for purifying smoke from the main exhaust pipe. Compared with the prior art, the exhaust pipe device capable of purifying the gas is simple in structure, good in waterproofing effect and good in heat dissipation effect, and can prevent rats and purify the discharged gas.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an exhaust pipe device for purifying gas. Background technique [0002] Most of the existing automobile exhaust devices are mufflers lying under the longitudinal beams, or arranged on the outside of the frame, but these arrangements have always had the problem that the exhaust port is easy to enter water, especially when it rains in summer, many roads are prone to water accumulation , causing the vehicle to be impassable, if the vehicle forcibly fords water, the water reaching a certain depth will enter the engine through the exhaust pipe, causing the engine to stall, and when it is re-ignited, it is also prone to engine explosion, which will bring unnecessary damage. The situation is serious and will cause personal injury or death; the exhaust pipe will become relatively hot after the car has been running for a period of time. Since many exhaust pipes are exposed outside the ...

[0002] Most of the existing automobile exhaust devices are mufflers lying under the longitudinal beams, or arranged on the outside of the frame, but these arrangements have always had the problem that the exhaust port is easy to enter water, especially when it rains in summer, many roads are prone to water accumulation , causing the vehicle to be impassable, if the vehicle forcibly fords water, the water reaching a certain depth will enter the engine through the exhaust pipe, causing the engine to stall, and when it is re-ignited, it is also prone to engine explosion, which will bring unnecessary damage. The situation is serious and will cause personal injury or death; the exhaust pipe will become relatively hot after the car has been running for a period of time. Since many exhaust pipes are exposed outside the car, it is easy to touch the exhaust pipe if you do not pay attention, and it is easy to damage the exhaust pipe. Man-made accidental injury; Exhaust gas pollution
